@rbsz , R Bonasera, You can try this before a hard reset, you can reset your home screen in Settings>General>Reset>Reset Home Screen Layout. Contacts and email icons will still be there probably, but may have got accidentally moved to another folder/file, so you could also search through your phone, find them and drag them back to home. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

It's time to speak out for your right to repair

We have a chance to guarantee our right to repair electronic
equipment—like smartphones, computers, and even farm equipment. This is a once-in-a-generation
chance to protect local repair jobs—the corner mom-and-pop repair shops that
keep getting squeezed out by manufacturers.

Join the cause and tell your state representative to support Right to Repair. Tell them you believe repair should be fair, affordable, and accessible. Stand up for your right to repair!
